Product DetailsProduct description:
Cement - concrete preparation process, in order to improve the performance of water reducing the need to use various types of admixtures. JS-PCWs polycarboxylate superplasticizer new generation of cement - concrete chemical admixtures. This is a class of polymer surfactant molecules having a comb structure. Since the molecule contains both a carboxyl group, a sulfonic acid group, an ester group, an ether group, and other groups of surfactants, it has adsorption, bleed air dispersion. Wetting, solubilization, stability augmentation and other features. Its application allows concrete with low water-cement ratio, low viscosity, high fluidity, retarded, fall protection and other features. Therefore, to improve the workability of concrete manufacturing, site preparation and is conducive to long-distance transmission, make high strength, high durability of concrete.
Because of its different kinds of cement and other additives have good compatibility, makes use of industrial wastes (blast furnace slag, fly ash, etc.) manufactures high-performance concrete as possible. Therefore, the application can greatly improve the manufacturing of concrete economic and social benefits.
Performance:
1) Uniformity of JS-PCWs
